Naomi Klein can be a bit heady and overwhelming at times. I started reading This Changes Everything because one of my best friends said I should—this is usually how it goes, right? I wasn't expecting to feel such a motivational pull quite like this passage gave me. I haven't been sure how to start with climate change—but admitting to my own climate denial feels like the right choice.

"I denied climate change for longer than I care to admit. I knew it was happening, sure. Not like Donald Trump and the Tea Partiers going on about how the continued existence of winter proves it’s all a hoax. But I stayed pretty hazy on the details and only skimmed most of the news stories, especially the really scary ones. I told myself the science was too complicated and that the environmentalists were dealing with it. And I continued to behave as if there was nothing wrong with the shiny card in my wallet attesting to my “elite” frequent flyer status.

A great many of us engage in this kind of climate change denial. We look for a split second and then we look away. Or we look but then turn it into a joke (“more signs of the Apocalypse!”). Which is another way of looking away.

Or we look but tell ourselves comforting stories about how humans are clever and will come up with a technological miracle that will safely suck the carbon out of the skies or magically turn down the heat of the sun. Which, I was to discover while researching this book, is yet another way of looking away.

Or we look but try to be hyper-rational about it (“dollar for dollar it’s more efficient to focus on economic development than climate change, since wealth is the best protection from weather extremes”)—as if having a few more dollars will make much difference when your city is underwater. Which is a way of looking away if you happen to be a policy wonk. Or we look but tell ourselves we are too busy to care about something so distant and abstract—even though we saw the water in the subways in New York City, and the people on their rooftops in New Orleans, and know that no one is safe, the most vulnerable least of all. And though perfectly understandable, this too is a way of looking away.

Or we look but tell ourselves that all we can do is focus on ourselves. Meditate and shop at farmers’ markets and stop driving—but forget trying to actually change the systems that are making the crisis inevitable because that’s too much “bad energy” and it will never work. And at first it may appear as if we are looking, because many of these lifestyle changes are indeed part of the solution, but we still have one eye tightly shut.

Or maybe we do look—really look—but then, inevitably, we seem to forget. Remember and then forget again. Climate change is like that; it’s hard to keep it in your head for very long. We engage in this odd form of on-again-off-again ecological amnesia for perfectly rational reasons. We deny because we fear that letting in the full reality of this crisis will change everything. And we are right."
